由于社会经济发展的需要,众多水利水电工程的建设实施,致使河流存在不同程度的截断。尤其是水库大坝依地势修建,借助水势落差产生的拦蓄动能发电。但这些工程截断了河流中洄游鱼类的通道,对河流内部生态环境循环系统造成破坏。鱼道工程是对水体与河流进行生态修复的补偿工程,因此建设过程中施工工艺的选取非常关键。而清水混凝土以其一次性浇筑成型、造型天然朴实的技术优势,在鱼道工程中得以广泛应用。
Due to the needs of social and economic development, the construction and implementation of many water conservancy and hydropower projects have led to the interception of rivers in varying degrees. In particular, the reservoir dam is constructed on the basis of the terrain, with the help of kinetic energy storage to generate electricity due to the drop in water potential. However, these projects cut off the passage of migratory fish in the river and caused damage to the circulatory system of the ecological environment within the river. The fish road project is a compensation project for ecological restoration of water body and river, so the selection of construction technology during construction is very crucial. The one-time water-pouring concrete pouring molding, modeling simple and natural technical advantages, widely used in the fish road project.
